Vert.x 3.4.0 is released!

Vert.x 3.4.0 has just been re­leased with many new ex­cit­ing fea­tures!

Vert.x 3.4.1 has been re­leased - the links have been up­dated

Since the be­gin­ning Vert.x has pro­vided a poly­glot run­time, this ver­sion sim­ply adds the sup­port of two major lan­guages of the JVM ecosys­tem: Scala 2.12 and Kotlin 1.1.

Some fea­tures are so im­por­tant that they de­serve to be taken to an­other level : the Vert.x Web Client fo­cuses on us­abil­ity fea­tures for build­ing web ap­pli­ca­tions. It ac­tu­ally builds upon the multi pur­pose and scal­able Http Client and in­her­its all its fea­tures.

Vert.x Rx­Java is a very pop­u­lar ex­ten­sion, 3.4 sup­ports the rx.Single re­ac­tive type as well as Observable re­ac­tive pull back pres­sure, com­bined with Vert.x Web Client, it is a very pow­er­ful combo.

You can now get a stream for large re­sult sets using JDBC client, with Rx­Java your stream be­comes nat­u­rally an Observable.

When it comes to IoT, Vert.x is a rel­e­vant choice thanks to its unique toolkit ap­proach that com­bines mod­u­lar­ity and re­duced foot­print, there are no doubts that the new Vert.x MQTT Server ex­tends Vert.x ca­pa­bil­i­ties in this field!

Every­one knows Kafka, every­one loves Kafka, the new Vert.x Kafka Client gives you every­thing you need to use Kafka the Vert.x way!

On the mi­croser­vices side, Vert.x gRPC will give a boost to your net­work­ing and Vert.x Con­fig fills the gap in our tool­box. In ad­di­tion we pro­vide now a full fledged Vert.x Con­sul client!

Dur­ing this re­lease cycle, we paid spe­cial at­ten­tion to se­cu­rity, en­sur­ing that Vert.x-Web ses­sions are safe and fol­low the OWASP rec­om­men­da­tions. Also, Vert.x web got many us­abil­ity im­prove­ments, with a re­vised OAuth2 setup and a new htdigest au­then­ti­ca­tion scheme.

De­vops hasn’t been for­got­ten with Vert.x Health Check, a key fea­ture in ap­pli­ca­tion mon­i­tor­ing.

On top of many bug fixes, here is a list of the most im­por­tant new fea­tures you can find in 3.4.0:

  • Vert.x In­fin­is­pan is a new clus­ter op­tion and su­per­sedes the JGroups op­tion
  • HTTP and Web client redi­rect han­dling
  • Zero-​config ser­vice prox­ies gen­er­a­tion with a processor clas­si­fied jar
  • a new SelfSignedCertificate to make easy to cre­ate tests and demos with TLS/SSL
  • Hys­trix met­rics in the cir­cuit breaker
  • Han­dle­bars tem­plates can now fully re­solve prop­er­ties passed to them
  • JsonOb­ject POJO map­ping con­ve­nience
  • Http com­pres­sion level op­tion
  • Groovy sup­port now uses ex­ten­sion meth­ods and does not gen­er­ate wrap­pers any­more
  • Drop­wiz­ard match met­rics can now have an alias
  • Rx­Helper method for adapt­ing an Observable<T> to a ReadStream<T>
  • Rx­Helper method for ad­pat­ing a Handler<AsyncResult<T>> to a Subscriber<T>
  • pro­vide Alpine and Busy­box docker im­ages

Vert.x 3.4.0 re­lease notes:

The event bus client using the SockJS bridge are avail­able from NPM, Bower and as a We­b­Jar:

Docker im­ages are also avail­able on the Docker Hub. The Vert.x dis­tri­b­u­tion is also avail­able from SD­KMan and Home­Brew.

The ar­ti­facts have been de­ployed to Maven Cen­tral and you can get the dis­tri­b­u­tion on Bin­tray.
